Double Detector Check Valve Assembly
The Double Detector Check Valve Assembly backflow preventer protects against backflow, by either back-pressure or back-siphonage, from a cross-connection between potable water systems and substances, in ‘medium hazard’ conditions. It is designed for use in fire service systems and allows monitoring of small draw-offs of water via the bypass.
